That USS Donald Cook indeed on a special mission what it is called. Ballistic missile defense.

"Donald Cook’s special mission"

"Donald Cook is the first of our permanently forward-stationed ballistic missile defense (BMD) warships, which we’ve been planning to put in the European theater as part of the Obama 'substitute' for the Bush 43 missile defense plan."

Instead of defending both Europe and the United States against missiles launched from South Asia, Obama’s plan defends only Europe [and presumably Israel as well], at least until 2018 and probably until well after.

This is strictly NAVAL BORNE BALLISTIC MISSILE DEFENSE! NOT CAPABLE OF SHOOTING DOWN AN INTERCONTINENTAL BALLISTIC MISSILE!

"Going on the assumption that Iran is the only source of a medium-range missile threat, the Obama plan stations BMD-enhanced Aegis warships in Europe, to rotate through routine patrol positions in the Black Sea and Mediterranean. Four Arleigh Burke destroyers . . . are destined to be permanently stationed in Rota, Spain to conduct most of these patrols."

Mr. Dyer not making any mention of an electronic warfare attack on the Donald Cook or sailors being traumatized.
